Answer:
The ratio of girls and boys = 9/7
Step-by-step explanation:
32 members there are 18 girls
so boys = 32 - 18 = 14
The ratio of girls and boys = 18/14 = 9/7
21 and 49 GCF is 7
So then you divide 7 out of both and get 7(3m-7n)
The formula for that area would be A=1/2xbxh so you would do A=1/2x3.5x3 and that equals 5.25
